Switch Control Destructive EPN Maintenance
Board Interface Test (#325)
This test is destructive.
This test writes test patterns into the EPN Maintenance circuit pack interface and
verifies that it can read back these test patterns successfully. Messages to or
from the EPN Maintenance circuit pack can be lost when this test is run.
any FAIL This failure indicates that communications with the Maintenance circuit
pack in the EPN is probably not possible. The EPN Manager I may not be
usable.
1. Run the Short Test Sequence several times to make sure the error is
occurring consistently, run the Long Test Sequence to reset the Switch
Control. Sometimes running the Long Test Sequence may clear the
problem. Remember the Long Test Sequence is destructive. Placing
and receiving calls is affected for several seconds.
2. Replace the Netcon circuit pack whenever it is convenient for the
customer (unduplicated system) or right away (High or Critical
Reliability system).
3. The procedure for replacing the Netcon circuit pack is described in
Chapter 6, ‘‘
Reliability Systems: A Maintenance Aid’’. The procedure
for doing the same in systems without High or Critical Reliability is
described in Chapter 5, ‘‘
Routine Maintenance Procedures’’.
PASS The EPN Maintenance circuit pack interface between the processor and
the Switch Control is working correctly. Test #325 is a more thorough test of
this interface but it is destructive.
